In the study of reliability of technical systems and shock models, the mean \linebreak residual life function plays an important role. In this paper, we consider the mean residual life of $k$th records under double monitoring. We introduce the notion of the mean residual life of $k$th records under the condition that the $m$th and $(m+1)$st shocks arrived before and after $t_1$, respectively, and the $(n+1)$st $(1 ≥ m < n)$ shock arrived after $t_{2}$ $(0 < t_{1} < t_{2})$. We study their respective monotonicity and aging properties. Some stochastic ordering \linebreak properties are also investigated. 2010 Mathematics Subject Classification: 62E10, 60E05 Full text: PDF
